GAGE FOR BEER-TANKS.

To all whom it may concern Be it known that I, WILHELM Gnrnssnn, a citizen of the United States, residing at St. Louis, in the State of Missouri,ihave invented new and useful Improvements in Gages for Beer-Tanks, of which the following is a specification.

This invention has reference to gages for use in conjunction with the cooling and storage tanks comprehended in brewing systems, and it proposes an improved mounting for a gage of the type indicated, which consists, briefly, in connecting the gage ends to the filling and discharge pipes of such tanks in the special manner hereinafter described.

An embodiment of the invention is illustrated in the accompanying drawing, whereo Figure 1 is a front elevation of a cooling tank having the gage connected thereto; Fig. 2 is an enlarged broken vertical section taken on the line 22 of Fig. 1; Figs. 3 and 4 are enlarged vertical and horizontal sectional views of the filling pipe, taken, respectively, on the lines 33 of'Fig. 4, and 44 of Fig. 3.

In said drawing, 1 indicates, generally, a tank of any suitable construction which may be utilized for storing or cooling the beer or in any of the other steps included in the brewing. It is inclosed or incased in a wall or covering 2 of cement, and its front face is provided with the usual test-cock 3, thermometer 4 and man-hole 5, and, also, when used for cooling purposes, with the stufiing boxes 6 and 7 in which are fitted the inlet and outlet ends of the brine coil, (not shown).

At its top and bottom, the tank is provided, respectively, with the filling pipe 8 and discharge or'emptying pipe 9, as represented in Fig. 2. The latter pipe and its adjuncts are preferably identical with those shown and described in my companion application, Serial No. 736,410, filed of even date herewith, and, in fact, form the subject matter of such application, for which reason it is deemed unnecessary to furnish a detailed description thereof in the present application. It may be stated, however, that the sections 10 and 11 of said pipe are disposed within a protective casing, the vertical member 12 of which is formed with a beveled flange 13 that is suitably anchored in place in an opening in the bottom wall of the tank, while the horizontal member 14 Specification of Letters Patent.

opens at its outer end through the concrete I casing 2. The pipe section 11 arranged within the casing member 14, projects outwardly through an opening in that member and is connected to a nozzle 15, the valve mechanism, (not shown), within said sections 10 and 11 being operated by meansof a push-rod 16, or the like. 7 i

The filling pipe 8, (see Figs. 3 and 4), comprises an angle or elbow pipeseotion 17 whose inner end is formed with 'a beveled flange 18, similar to flange 13, which fits in a seat 19 in the top wall of the tank and is anchored against turning by means of spurs 20 similar to the spurs 28 on the flange 13. The lower arm of this section is exteriorly threaded and carries a clamping nut 21 and washer 22, while the free end of the upper or horizontal arm, which is similarly threaded, is fitted in the interiorly threaded end of a short pipe section 23 that forms a continuation of the said arm. At its outer end, section 23 carries a cap 24, provided with spaced outer and inner concentric side walls 25 and 26 between which said section end fits, the space between said walls receiving packing 27 which is compressed, when the cap is turned in the proper direction, to obtain the requisite tight oint. The inner surface of the cap wall 25 is threaded, as shown, for engagement with the threads on the adjacent end of section 23.

The gage glass 29 is connected at its ends to suitable fittings carried by the pipe sections 23 and 11, and these fittings, in the construction illustrated, comprise curved elbowjoints or unions 30 and 31, which, in turn, are attached to lateral nipples 32 and 33, the pipe section 23 being provided with a pair of such nipples located at diametrically-opposite points- Said nipples are connected directly to the corresponding pipe sections,

either integrally or otherwise, and are provided, each, with a rotatably mounted valve 34 having an opening 35 and an operating handle 36. The valves are, or may be, substantially identical with one another, and, hence, the description of one will be sufficient.

As shown in Fig. 4, each nipple is provided with a pair of lateral branch nipples 37 which are located opposite each other and are exteriorly threaded, and these branch nipples carry interiorly-threaded caps 38 having openings wherein the ends of the valve stems are journaled, suitable packings being interposed between said caps and the nipple ends. The outer ends of the main nipples 32 and 33 are likewise threaded exteriorly, the ends of the nipple 33 and the nipple 32 directly thereabove being engaged in the one end of the unions 31 and 30, the said unions, at their other end, receiving the ends of the gage glass. The valves in the two nipples which are in direct communication with the gage glass are normally open, as will be understood, to permit the beer to flow into said glass. The other nipple in the filling pipe and its valve may be used to control the escape of the air and gas collecting in the upper part of the tank, or for any other purpose of a like nature Without requiring the cap 24L being removed or communication between the gage and the tank being cut off.

In a device of the class specified, the combination of a tank, a filling pipe connected to the top of the tank and including an outwardly projecting section provided with a removable screw cap and diametrically opposed nipples arranged at right angles thereto and opening thereinto in rear of said cap, each nipple having an exteriorly operative valve, a discharge pipe connected to the bottom of the tank and provided with a single lateral valved nipple above the outlet end thereof, and a gage glass connected at its upper end to one nipple of the outwardly projecting filling pipe section and at its lower end to the single nipple of the discharge pipe, the remaining nipple of the outwardly projecting filling pipe section being used to permit the escape of air and gas from the upper part of the tank without disturbing the closure of the filling pipe or cutting off communication of the gage glass with relation to the tank.

In testimony whereof I have hereunto set my hand.

VILHELM GRIESSER.
